Plot routes on SHN

See what highway corridors show up.

Can span multiple operators. These corridors, if improved, would benefit all operators.

Brainstorm

Filter to just routes that are on SHN.

• In top 75% of trips_all_day_per_mi...mostly to select out where trips occur on highways OR
• <= 25 mph average for RT speeds, relatively slow speeds for routes that are running on SHN! Only if RT info is present (not always available for express buses)

Highway 1 in District 4, near Golden Gate Park. PCH (1) in District 7. Both are technically part of SHN, but have much slower speeds, or are more like arterial segments.

Change colormap to go above 30 mph because that was more applicable to urban speeds.

Maybe different scales by RouteType, because Interstate/US vs State is different speeds. See how speed limit can be brought in.
